how to omit in sails.js two or more sockets in sails.sockets.broadcast?

I need to know how to omit in sails.js two or more sockets in sails.sockets.broadcast? I tried this:

 function sendMessage(data){
   var socketIds = ['socketId1','socketId2'];
   sails.sockets.broadcast("room","event",data,socketIds);
   //sending data to ALL sockets in the room :/
 }

but it doesn't work.

I need know this because I need omit the sockets which belong to the same session. (example: session of user in computer browser and android browser)

somebody help?
